If you want Hooker headers, Summit Racing has them listed. I've used them, and been around cars with them, for years and they're pretty good, too. Expensive, though. About $430 when I looked them up a minute ago. Equal length, 18 ga tubing. They should have a good, noticeable header tick/spit at idle. The exhaust slaps the tubing where it turns, and makes a distinctive noise. The heavier-gauge tubes aren't as prominent a sound, but Hooker does make noise.
